HEPLISAV-B vaccine is the first and only adult hepatitis B vaccine approved in the U.S., the European Union and Great Britain that enables series completion with only two doses in one month. Hepatitis B vaccination is universally recommended for adults aged 19-59 in the U.S.

• HEPLISAV-B vaccine net product revenue for the fourth quarter and full year 2023 were approximately $51.1 million and $213.3 million, respectively, representing year-over-year growth of approximately 46% and 69% compared to the fourth quarter and full year 2022.

• Driven by the Centers for Disease Control and Prevention's Advisory Committee of Immunization Practices (ACIP) universal recommendation for adult hepatitis B vaccination, the hepatitis B vaccine market continues to expand in the U.S. and Dynavax believes the U.S. market has the potential to grow to approximately $800 million by 2027, with HEPLISAV-B well-positioned to achieve a majority market share.

Clinical Pipeline

Shingles vaccine program:

Z-1018 is an investigational vaccine candidate being developed for the prevention of shingles in adults aged 50 and older.

• Dynavax recently submitted an Investigational New Drug Application (IND) to the U.S. FDA to support initiation of a Phase 1/2 trial of Z-1018 in the first half of 2024.

Tdap vaccine program:

Tdap-1018 is an investigational vaccine candidate intended for active booster immunization against tetanus, diphtheria, and pertussis (Tdap).

• Dynavax plans to submit an IND to the U.S. FDA to support the initiation of a Phase 2 human challenge study of Tdap-1018 in the second half of 2024, upon completion of the independent study conducted by the Canadian Center for Vaccinology to establish the human challenge dose.

Plague vaccine program:
